Profile: With Kevin Gregg no longer in Chicago, there is an opportunity for someone to step into the closer role. Pedro Strop and Jose Veras may be the favorites to take over the role, but Parker should be in the mix as well. In his favor are a solid 46.1 innings last year and some experience closing in the minors. He posted a 2.72 ERA (2.88 SIERA) with a 28.2% strikeout rate and 7.7% walk rate. The rates were much better than the league averages for relievers, which were a 21.7% K% and 8.9% BB%. Unless Parker happens to be named the closer in Spring Training, though, he's not worth drafting. But he's definitely a guy to watch when monitoring potential closers in-season. (Brett Talley)

The Quick Opinion: With Kevin Gregg gone, someone has a chance to assume the closer role in Chicago. Parker probably isn't the favorite, but solid stats last year and experience closing in the minors mean he could be in the mix.

Profile: Parker has been slaying minor league pitching over the past two seasons, and with a 2.72 ERA season in recent memory, he could play a significant role in the back end of the Cubs bullpen if he can recapture that 2013 sparkle. Joe Maddon has shown a willingness to put inexperienced relievers into closing or setup roles, so do not be surprised if Parker can find a few saves in 2014. That being said, he's likely behind Jason Motte to start the season and certainly behind Hector Rondon. Pedro Strop might be a step further up the ladder too. Either way, Parker is a former Triple-A closer who made the Pacific Coast League look like a pitcher's league. Even though he's a late bloomer (age 30 in 2015), he is worth keeping an eye on.

The Quick Opinion: Parker might not be first in line for a closing or setup role in Chicago, but his minor league numbers have been filthy recently, and he has a 2.92 SIERA in his career. There could be an elite reliever hiding behind last season's 5.14 ERA.
